Detecting Cylinder Internal Leaks
An internal leak is caused by a damaged seal inside the hydraulic cylinder (see 1 on Figure 5-29).
Because the cylinder is leaking oil inside (bypassing), a certain amount of pressure is lost, reducing
the efficiency of the cylinder and its capacity to push and/or pull.
If the packer cylinders are bypassing, the seal inside the cylinder may need to be replaced.
To detect internal leaks in packer cylinders:
1.
Apply all safety measures, and apply the parking brake.
2.
Pull on the red emergency S
TOP
button.
3.
Start the engine and engage the hydraulic pump.
4.
Fully extend the packer cylinders and disengage the hydraulic pump.
5.
Disconnect the packer extend proximity switch. This prevents the packer from returning to its
initial position.
6.
Disconnect and plug hose “A”.
7.
Engage the hydraulic pump.
8.
Push the green button and see if oil is leaking from port “A”, then push the emergency S
TOP
button.
If oil leaks out of port “A” when pressure is applied, there might be an internal leak; replace or
repair the cylinder.
